Does input shaft have a "reservoir tip" (non splined)? Thats a lock up input shaft. If you want to run the lock up as a slipper, just dont hook up the sensor, but I gotta ask why not: cruising and flip the switch..you get a 250 rpm reduction in engine speed with no other loss. In theory, the Idea is to route 12V to switch through a 45-55 psi hobbs switch from the governor pressure port, and then put a rocker switch in the cab. Pressure port will open under ~45 MPH and not allow 12V to get to electically operated OD fluid control solenoid so it will disengage when you slow down and cut back in at speed if you have the switch activated. Computer took coolant, speed, vacuum load, etc into consideration when stock. See if 12V applied to that switch makes any sound in the trans, maybe a little thunk or click? (maybe nothing if internal pressures are under a certain psi) All I see is 2 and 3 pin connectors.....Here is a single wire switch advertised
